Respiratory Syncytial Virus (RSV) Antigens and Antibodies

Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract illness in children globally. Sino Biological has developed a comprehensive collection of RSV-related reagents for viral research (18 antigens, seven antibodies, 80+ ELISA Kits, and cDNAs) that cover RSV A and B from over five strains, which can support therapeutic antibody, vaccine, and immunodiagnostic assay development.

Featured Product: Validated RSV Pre-F Trimer Protein
The Fusion (F) protein presents as a trimer on the surface of the RSV virion and plays a key role in virus invasion. Obtaining stable pre-fusion (Pre-F) proteins is crucial for RSV vaccine development. Sino Biological has developed a stable pre-fusion protein with a 90% trimerization ratio validated by SEC-MALS, which can support the development of RSV vaccines.

  • Stable Prefusion Conformation Verified by Conformation-specific Antibodies
  • Trimer purity ≥90%, validated by SEC-MALS
